In order to better accomplish any goals, set deliverables and scheduling must be determined. Having these paths set will enable the team to effectively determine current status. Deliverables The deliverables to be accomplished for the fall semester are as follows: • Base circuitry to interface sensors to computers • Base Labview program • Complete design and CAD model • Hip Joint The deliverables to be accomplished for the spring semester are as follows: • Model support stand • Member(Tibia and Femur) • Ankle joint • Knee joint • Foot marker • Final circuitry contained within package • Final Labview program with export functions Schedule In order to best accomplish the model, the L2m Team has prioritized its deliverables in the order as presented previously. In general, the L2m Team plans to complete the project in the following fashion: The team currently is finishing identify the customer requirements this week. The team will also begin examining appropriate sensors to use for measuring joint angles this week. After an appropriate sensor has been selected, the L2m Team will focus on designing the three kinematics joints along with the members, stand and foot marker necessary for mimicking a normal human leg. While designing the kinematic joints the team will also design static joints that will enable the model to mimic a deformed limb. This time set aside for designing will include time to benchmark and research the kinematics of a human leg and previously designed joints and hinges used in industry. After designing the team will order the necessary parts, manufacture, mount the sensors, test and refine. The accomplishments outlines previously are estimated to be completed by the end of March in 2007. This time line should prove to be sufficient time. Should this schedule prove too aggressive, the foot maker tracking apparatus will be excluded from the model. Should theschedule be not aggressive enough, additional features will be added to the LabView program to include data produced by the foot trajectory apparatus. To see specific dates for deliverables to be accomplished see Attachment 1. Conclusion Identifying the deliverables and updating the schedule enables the L2m Team to direct efforts in a more efficient way. The new schedule will also enable the team to not fall behind and finish the model by April 15, 2007.ID Task Name Duration Start Finish Predecessors1Sensors, electronics and soft102 days Mon 9/25/06 Mon 3/19/072 Order test electronics 5 days Mon 9/25/06 Fri 9/29/063 Test in Labview 7 days Mon 10/2/06 Tue 10/10/06 24 Select sensors 4 days Wed 10/11/06 Mon 10/16/06 35 Order additional sensors 5 days Tue 10/17/06 Mon 10/23/06 46 Labview/Refine 30 days Tue 2/6/07 Mon 3/19/07 5,4378Joints 51 days Tue 10/17/06 Mon 1/29/079 Design 12 days Tue 10/17/06 Wed 11/1/06 410 Order 5 days Thu 11/2/06 Wed 11/8/06 91112Hip 7 days Thu 11/9/06 Fri 11/17/06 1013 Manufacture 5 days Thu 11/9/06 Wed 11/15/0614 Test/mount sensor 2 days Thu 11/16/06 Fri 11/17/06 131516Ankle 7 days Wed 1/3/07 Thu 1/11/07 3117 Manufacture 5 days Wed 1/3/07 Tue 1/9/0718 Test/mount sensor 2 days Wed 1/10/07 Thu 1/11/07 171920Knee 7 days Mon 1/15/07 Tue 1/23/07 4121 Manufacture 5 days Mon 1/15/07 Fri 1/19/0722 Test/mount sensor 2 days Mon 1/22/07 Tue 1/23/07 212324Foot 4 days Wed 1/24/07 Mon 1/29/07 2225 Manufacture 3 days Wed 1/24/07 Fri 1/26/0726 Test/mount sensor 1 day Mon 1/29/07 Mon 1/29/07 252728Support Stand 8 days Mon 11/20/06 Tue 1/2/07 1429 Design 2 days Mon 11/20/06 Tue 11/21/0630 Order parts 3 days Mon 11/27/06 Wed 11/29/06 2931 Machine and Assemble 3 days Thu 11/30/06 Tue 1/2/07 303233Members 23 days?
